    no you can't.
    both engines came from 3rd gen. prelude. to mounts were diff. from 3G accord.
    the only engine that will drop in without any modifications is JDM B20A from 3G accord or 2G lude. Every other engine will need to be adapted.

    talk to "B20aturbo" guy on this board, he can get JDM B20A engines, the problem he can only get auto tranny. manual trannies are very hard to find.

    does the 1988-91 lude come with b20 or have a 5-speed tranny that can fit onto a b20??

    In Europe the B20A1 is the 2nd gen prelude engine.

    No.

    Everything you need to know about B20A's has been thoroughly discussed in this forum. Please spend a few minutes and browse the threads.

    you can't swap any 5 speed from lude or anyother car. JDM B20A had its own 5 speed design. no tranny from other engines will bolt up to that motor.
    you have to find JDM 3G B20A tranny if you want 5 speed.

    now i see why its hard to find 5-speeds for this engine !

    after looking at the website for modding the A20's, i might go do that.

    if i buy a Built 400hp 8000rpm Capable Shortblock, does it come with heads, head gasket, valves, intake manifold, Block, all that kinda stuff?? my motor has 160,000 miles on it, if i turbo that, it would blow apart .

    i love Accord Central, im not doing an engine swap for a b20 or b18 .


    all info on accord central would be greatful

    edit: i was just thinkin', i need a stronger clutch when im done tuning this car. also do i need to get a new tranny to handle so much power? i plan on gradually getting everything at the website!!
